Here's some updated but not fully up to date photos of my hatch
Here it is covered in linen. You can see I did a really mediocre job cutting my bias strips...I just wasn't into it for some reason that night an I should have just let it go. But in the end wobbly edges won't matter as long as the foam is covered (and it is)



It got primed with Glidden Gripper.

And painted to match blue outside, white inside.


I'm using this double bulb seal from McMaster to seal the edges. It is just about as wide as the wall of the foamy it's stuck to. I am very happy with it thus far anyhow.

The whole thing is actually installed now with a living hinge, grey putty tape, and aluminum strips and all. I will try for some photos of that soon. I was surprised I didn't have any actually. The only problem so far is that the hatch weighs so little that it doesn't compress the seal with its own weight. So it will be the job of the latches to hold it closed. Right now the seal pushes up on it enough that it is about 3-4" away at the bottom when just hanging unsupported. It does close with a very small amount of pressure to compress the seal.
